The plain dresses are actually quite comfortable as well. One neighbor was "the village blacksmith" in Missouri Town 1850, which is a reinactors village near by. He is all about that era in time and the ancient Vikings. The other neighbor and his whole family is involved in the Renaissance Festival near us. He was even "king of England for several years. We also love the Renaissance Festival. We are pass holders and dress for the fest. My son-in-law makes chain maille and usually is a knight or ranger, daughter is a faerie or some other thing. I am "a farmers wife" (who would have guessed that!)

We also have a covered wagon that gives historical tours driving down our street! You never know if you will be greeted by a homesteader (me), a frontiersman or a knight in shining armor around here!
So glad you mentioned the "standing hay" idea. So many people around here just don't understand that idea. On the Kansas range lands standing hay is what feeds the range cattle for a good portion of the winter in some cases.
One drawback to that is that grass when allowed to mature into standing hay loses a lot of nutritional value. This said, I believe if you used this early in the season and the animals are still fat from summer grass or when weather was being mild and they did not need the extra calories, you could save a lot of work that usually goes into haying a field then feeding the hay. This way you could feed the quality hay when the animals really need it most, like hard cold spells or late winter. Even though hay loses some nutrients while you hold it in a barn or under a tarp, it would still be higher than the standing hay.
I am all about the rotation grazing method that you describe. I have read a lot about it as well. I have had horses most of my life and spent a lot of time learning about improved pastures and I think your ideas will work great. I would still over seed that lawn. You do not have to use as much seed for it to take with the methods that you are describing. Just seed right after a rotation when the grass is shortest. If you are running pigs, cattle or horses you should also invest in a harrow. Running a harrow around right after a rotation will spread out any poo cakes allowing the sun to kill any larva, loosen up any thatch, and over all really help the pasture. Sheep and goats have such little poo it may not be as important. Another thing to consider is liming the pasture. Manure tends to make ground acidic and adding lime (or wood ash) will help keep the ground sweet and productive.
As far as "grass" finishing those beef cattle I read an interesting article about finishing cattle on standing corn. The idea works the same as the rotational grazing - using electric fence to divide into small pastures.
Plant the corn field in blocks all at the same time. When it comes time to finish the beef they go in on the young corn - eating until it is level. Then they are moved to the next block, which is by now more mature, and eat that down. Block by block the cattle are moved until they "finish" when the corn does. Eating the last corn block when the corn is nice and ripe, stalks and all! When that field is finished so are the beef - which are then loaded for slaughter.
It would take a lot of good planning and some initial hard work, but it sounds like it would work and corn IS a grass. This is supposed to help the field, due to the manure as well as the cattle. Have you ever heard about this before?
